ABSTRACT
PURPOSE: Dialysis patients have a different response than the non-dialysis population to infection with COVID-19. This study evaluates the prevalence of infection and lethality in patients receiving hemodialysis or peritoneal dialysis in Panama, compared to non-dialysis adult population, and reports of adverse events of vaccination. METHODS: This is a prospective, multi-center cohort study of spatients aged 18 years or older and receiving in-center hemodialysis or ambulatory peritoneal dialysis in 13 centers in Panama from March 2021 to 2022. For comparison with general population, the study used an extended period of two years. RESULTS: A total of 1531 patients receiving dialysis treatment accepted to participate. PD patients represented an 18% of study patients. Lethality was higher in peritoneal dialysis patients with COVID-19 infection than in hemodialysis in the study group (p 0.02). Total deaths in dialysis patients for 2020 were 156 patients, before vaccination; 79 in 2021; and 25 for the first trimester of 2022. Lethality for the period of 2020-2022 was 9.3% for dialysis patients and 0.2% for non-dialysis population. There was no difference in symptoms in first dose, but with second dose, hemodialysis patients reported fewer symptoms than peritoneal dialysis patients (p < 0.0001). CONCLUSION: Ninety one percent of people in the country received BNT162b2 Pfizer BionTech vaccine. Lethality decreased from 30 to 5% once vaccination was available. There were no severe adverse effects and symptoms reported were less frequent than in general population, probably due to low reactogenicity in dialysis patients, or better tolerance to pain.

Antecedentes y objetivo: Los pacientes con Enfermedad Renal Crónica (ERC) en Hemodiálisis son pacientes que tienen condiciones que los hacen pacientes de riesgo para la infección por COVID-19. Los pacientes en hemodiálisis han sido un grupo muy afectado, debido a que no pueden suspender sus tratamientos para mantener el aislamiento domiciliario, lo que aumenta su exposición y riesgo a infección por COVID-19. Para evaluar el comportamiento de la infección por SARS-CoV-2 en los pacientes en hemodiálisis crónica en Panamá, realizamos un estudio prospectivo de los pacientes infectados por COVID-19 en las Unidades de Hemodiálisis de la CSS de todo el país, para determinar las características de los pacientes afectados, los síntomas que presentaron, su evolución clínica y el desenlace de los pacientes infectados. Materiales y Médodos: Realizamos un estudio longitudinal descriptivo prospectivo multicéntrico de los casos positivos que se diagnosticaron desde el 15 de julio hasta el 31 de diciembre de 2020 en las 14 Unidades de Hemodiálisis de la CSS del país. Resultados y conclusiones: Fueron incluidos un total de 333 pacientes en hemodiálisis con diagnóstico positivo para infección por SARS-CoV-2, de un total de 2194 pacientes que realizan hemodiálisis en las Unidades de la Caja de Seguro Social. El 59.5% de los afectados fueron de sexo masculino. La edad promedio fue de 56.75 años (DS 15.1 años). La Tasa de Mortalidad encontrada en nuestro estudio fue de 26%. La incidencia acumulada de COVID-19 en pacientes en Hemodiálisis fue de 16% para el período de estudio del 2020. (provisto por Infomedic International)
Background and objective: Patients with Chronic Kidney Disease (CKD) on Hemodialysis are patients who have conditions that make them patients at risk for COVID-19 infection. Hemodialysis patients have been a highly affected group because they cannot stop their treatments to maintain home isolation, which increases their exposure and risk of COVID-19 infection. To evaluate the behavior of SARS-CoV-2 infection in patients on chronic hemodialysis in Panama, we conducted a prospective study of patients infected by COVID-19 in hemodialysis units throughout the country, to determine the characteristics of the affected patients, the symptoms they presented, their clinical evolution and the outcome of the infected patients. Materials and Methods: We conducted a multicenter prospective descriptive longitudinal study of the positive cases that were diagnosed from July 15, 2020 to December 31, 2020 in the 14 Hemodialysis Units of the Social Security Fund of the country. Results and conclusions: A total of 333 hemodialysis patients with a positive diagnosis for SARS-CoV-2 infection were included, out of a total of 2194 patients undergoing hemodialysis in the Units of the Social Security Fund. Fifty nine percet of those affected were male. The mean age was 56.75 years (DS 15.1 years). The Mortality Rate found in our study was 26%. The cumulative incidence of COVID-19 in hemodialysis patients was 16% for the 2020 study period. (provided by Infomedic International)
